Hello everyone,  
I am doing simulations using PyLith 3.0.3 for different slip cases in the Chilean subduction zone. For the forward model, I used as reference the step02\_coseismic included in the 3-D subduction examples. However, now I need to calculate the Green’s functions, but as the syntax changed with the 3.03 version and as there is no reference example, I wanted to know how to do it or maybe a reference to something that I can emulate. Here I upload my pylithapp.cfg in case if its needed  
[pylithapp.cfg](https://community.geodynamics.org/uploads/short-url/uEX7kGXVu595UOFq0k6V8Y05koZ.cfg) (5.4 KB)

See [examples/strikeslip-2d/step05-greensfns](https://pylith.readthedocs.io/en/latest/user/examples/strikeslip-2d/step05-greensfns.html) for an example of using Green’s functions in PyLith v3.0.
